Abstract

Vorgeschlagen wird ein Verfahren zum Wiederaubau des Bremsdruckes nach einer Entlüftung in einem Anti-Blockier-System (ABS) eines Kraftfahrzeuges. Hierzu werden sowohl der jeweils letzte Abregeldruck (Pmax) als auch der Haltedruck (Pmin) während der ABS-Regelzyklen mittels eines Drucksensors (6) erfaßt und in der ABS-Elektronik (9) gespeichert. Der anschließende Druckwiederaufbau wird so gesteuert, daß er zunächst einen steilen Gradienten und anschließend einen flachen Gradienten aufweist, wobei der steile Gradient eine Funktion von Pmax und Pmin ist, und der flache Gradient eine Funktion von Pmax ist.
